祁雨沟次火山斑岩型金矿床成矿系统分析及找矿意义

Analysis of the metallogenic system of Qiyugou subvolcanic porphyry gold deposit and its prospecting significance

河南金源黄金矿业有限责任公司是建矿已近40年的老企业,保有储量持续下降,急需增加新的矿产资源。通过对祁雨沟金矿区成矿地质背景、矿床地质特征及成矿规律的深入研究,发现该矿区内的隐爆角砾岩型金矿体、石英脉型金矿体、花岗斑岩网脉型金矿体,均分布在一个成矿系统内,并以此建立祁雨沟次火山斑岩型金矿床成矿系统,应用该成矿系统指导找矿,取得了重大突破。

Henan Jinyuan gold mining company is a company with a history of nearly 40 years. Its available reserve has been decreasing,so the company is in urgent need of new mineral resources. Through thorough exploration of the metallogenic settings,deposit geology characteristics and ore-forming rules in Qiyugou gold mining district,it is found that the cryptoexplosive breccia gold orebody,quartz vein gold orebody and granite porphyry stockwork gold orebody are all distributed in the same metallogenic system. Based on that,the metallogenic system of Qiyugou subvolcanic porphyry gold deposit is established,the application of which has achieved breakthroughs in prospecting guiding.
